extract color palette from image - autofill color ramp

I believe both of this would be useful and also combined as a single opp within the color ramp.

So, suggestion: a) somewhere in blender allow selection of an image to extract a color palette and create a named palette from the colors. b) the functionality in the Color Ramp material node to load colors from a palette c) the funcitonality in the Color Ramp material node to load colors directly from the most common colors in a selected image.
